A protractor measures the degree of angles and circles.
Use a protractor or use the formula: (n-2)*180 = sum of degrees whereas 'n' is the number of sides of the shape or polygon

Not usually. It is mostly made of plastic.
Protractor
A protractor is a shape: semi-circle or full circle, that has degrees marked around the edge. Place the marked centre of the protractor on (for example) the corner of two lines forming a right-angle. The bottom line will be zero, while the vertical line will cross the 90 degrees mark of the protractor, so proving that a right-angle is 90 degrees.
who invented the protractor?
A full protractor is is a protractor that goes 360 degrees around.
